Examination Of The Magnitude And Timing Of Hip Flexion Torque In High Degree Of Difficulty Forward Somersault Dives On The 3m Springboard, Brendon Ferrier
Examination Of The Magnitude And Timing Of Hip Flexion Torque In High Degree Of Difficulty Forward Somersault Dives On The 3m Springboard, Brendon Ferrier
Theses: Doctorates and Masters
While there has been much research published on the kinematics and kinetics of forward dives from a springboard, very little has been done on the effect the timing and magnitude of hip flexion torques has on forward dives. The purpose of this study was to investigate the relationship between the timing and magnitude of hip flexion torques prior to the take-off and the vertical velocity at take-off in high demand rotational forward dives. Twenty-six elite divers (14 males and 12 females) competing in the United Kingdom leg of the 2001 FINA Diving Grand Prix performed high demand rotational dives. The …
The Effect Of Eccentric Exercise Velocity On Selected Measures Of Muscle Function And Soreness Of The Human Elbow Flexors In Untrained Males And Females, Dale W. Chapman
The Effect Of Eccentric Exercise Velocity On Selected Measures Of Muscle Function And Soreness Of The Human Elbow Flexors In Untrained Males And Females, Dale W. Chapman
Theses: Doctorates and Masters
Eccentric contractions, where a muscle is repeatedly lengthened while generating torque, result in decreased muscle function and muscle soreness. This study was designed to determine whether there was a difference in muscle response of the elbow flexors from untrained subjects (n = 12) between a bout of high intensity eccentric exercise at 30°•s-1 (LVE) compared to the equivalent at 210°•s-1 (HVE). Subjects performed 120 seconds of eccentric exercise of the elbow flexors using a Cybex 6000 Isokinetic Dynamometer. At 30°-s-1, a total of 30 repetitions were required whilst at 210°•s-1, 210 contractions were performed (at a 1:7 work/rest ratio). Both …
